Descriptions

vantage6 is a framework to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). In affected versions a node does not check if an image is allowed to run if a `parent_id` is set. A malicious party that breaches the server may modify it to set a fake `parent_id` and send a task of a non-whitelisted algorithm. The node will then execute it because the `parent_id` that is set prevents checks from being run. This impacts all servers that are breached by an expert user. This vulnerability has been patched in version 4.1.2. All users are advised to upgrade. There are no known workarounds for this vulnerability.

vantage6 es un framework para gestionar e implementar tecnologías que mejoran la privacidad, como el Federated Learning (FL) y la Multi-Party Computation (MPC). En las versiones afectadas, un nodo no verifica si se permite ejecutar una imagen si se establece un "parent_id". Una parte malintencionada que infrinja el servidor puede modificarlo para establecer un "parent_id" falso y enviar una tarea de un algoritmo no incluido en la lista blanca. Luego, el nodo lo ejecutará porque el `parent_id` que está configurado impide que se ejecuten comprobaciones. Esto afecta a todos los servidores que son vulnerados por un usuario experto. Esta vulnerabilidad ha sido parcheada en la versión 4.1.2. Se recomienda a todos los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
